Awesome idea, it is hard to try for now but it could be very useful.
I especially like simple clip and resize feature but can't try them right now...
But also get it if you mean you're not in a good place to test the tool at the moment haha
To improve the tool it would be nice to play the part clipped with the sound to check if it's ok. Also the tool failed to load one video.
Good job !
When it failed to load the video, did it show a convert option that failed to load it as well? I think there are some limitations to the ffmpeg.wasm compile. Do you know the extension, or any details of the codecs, etc?
